This is how it works:
views/helpers/MyHelper.php contains class Zend_View_Helper_MyHelper which has a function called myHelper()
Also, if you add a function called setView() to your class, then the View will pass you an instance of itself before it calls your view helper function.
i.e.
Class Zend_View_Helper_MyHelper { protected $_view; public function setView($view) { $this->_view = $view; } public function myHelper($myVar) { return $this->_view->escape($myVar); } }
